AbstractThe rates of diffusion of CH4, nC4H10, iso‐C4H10, and C4F10 into well‐characterized single crystals of sodium mordenite were studied at 25°C to 100°C., using a rapidly responding constant‐volume system. The diffusion coefficients are of the order of 10−8 to 10−9 sq. cm/sec.

Materials Research Bulletin, 1978
Mordenite from Challis Valley, Idaho, was ion-exchanged with RbCl2 solution to ∼Rb8Al8Si40O96·nH2O. After dehydration at 340°C for 1 day, the crystal structure was determined at room temperature. Earlier attempts to dehydrate crystals at higher temperature led to disintegration, and even the present crystal fractured.

Applied Catalysis A: General, 1999
Abstract Hydroconversion of n -octane and n -hexane was investigated on a series of platinum loaded mordenite samples with varied framework aluminium (FAl) content. In agreement with previous authors, it was observed that the rate of hydroconversion is first increased almost linearly with the number of FAl per unit cell, reached a maximum then ...

Decaline conversion on mordenite
Zeolites, 1990The spectrum of gaseous products of the decaline conversion at 450°C on H-mordenite with propane and isobutane as main products is a typical one for a catalytic cracking reaction of, for instance, C 5 - or C 6 -alkanes. Therefore, it is concluded that in the first step decaline is fragmented under formation of acyclic species and in the second step ...

Study of Mordenite Crystallization III: Factors Governing Mordenite Synthesis
1984Abstract Mordenite is synthesized from different aluminosilicate gels in sealed pyrex tubes at 165°C. Its crystallization domain is established for these conditions and the coexisting phases are identified. Differences with published data are explained assuming partial dissolution of the silica-rich pyrex glass.

The crystal chemistry of mordenites
Contributions to Mineralogy and Petrology, 1975Mordenite is a zeolite whose approximate composition is (Na2, K2,Ca)4[Al8Si40O96] 28 H2O. Unit cell dimensions, determined by X-ray powder diffractometry for 35 natural samples, fell within the following ranges: a=18.052–18.168, b=20.404–20.527, c=7.501–7.537 A. The indexed powder pattern of a typical sample is reported.
